VTK开发程序能大大缩短图像，图像开发时间，尤其是3维图像图像，那么为何我直至今日还没有真正花费时间去学习VTK开发，与此作一番比较，看看自己是否到底值得花费如此时间？
目前，我所使用的3d程序开发 主要使用MSVC6以及OPENGL基础上完成，但是opengl对于三维开发而言是很底层的一个东西，虽然有时底层的东西开发很好用，至少学习使用起来不是那么麻烦，可能就是稍微花费点时间而已，但是当真正用到需要作一些项目或者一些实验的时候，往往弊端就暴露出来了，有时为了实现一个以前实现过的东西，不得不重新书写代码，因为自己在书写代码的时候一般性而言是不会写成标准库那样子的，so一般自己书写的代码只有当时有效，事后只能作为参考的东东而已，而且opengl开发的话，大多很底层的东西大多当时是明白的，过了一段时间之后在回头回去看这些代码的时候，已经分辨不清什么是是么了，如果vtk开发的话，至少使用了标准的库，可能第一次性开发的时间比较长，原因是自己对于VTK的不了解觉，但是一旦掌握这个工具后估计后期开发将会相当的省时间的，关键就是这个前期的学习周期比较长，不知道能不能在有限的时间内搞定下来。
so，vtk的学习现在win平台上操练下然后再考虑移植到linux上继续，呵呵，然学习如何自己封装自己的vtk数据。
安装是个很漫长的过程，cpu连续保持100%负荷运作10多分钟：
然后，好不容易把vtk的lib文件全部ok了，然后发现example中的vtkmfc例子不能正常运行，原始是缺失vtkmfc.lib文件，可是该文件并不存在，然后找到了以下这篇faq：

Check 'Show Advanced Values'. Click on Configure, CMake will ask you to create the VTK-VC++ folder Put setup parameters exactly like that: - BUILD_TESTING = OFF - VTK_USE_ANSI_STDLIB = ON - VTK_USE_HYBRID = ON - VTK_USE_PATENDED = ON Click twice again on 'Configure' and then click on 'OK'.

Second solution is make a subclass of vtkMFCWindow, then remove the msg handle from vtkMFCWindow, make some of mine.

Ok - so here's the situation: I writing an app using Visual Studio C++ using both MFC and VTK. Consquently I'm using the vtkMFCWindow to the the vtk display. The project extends the vtkSDI example (which may have a bearing on how things are done.) I would like to be able to interact with the vtk window as already happens, but it would also be nice to be able to use keyboard and mouse interaction for other parts of the project. To enable a context menu I created a subclass of the vtkInteractorStyle which then sent the WM_CONTEXTMENU command when the right mouse button was clicked (but not moved). This seemed an ok solution, but isn't very extensible for other interactions. For instance I would like to modify my document class when certain keys are pressed, and it seems somewhat long winded for the interactor to get the active document and call the appropriate routine, when it would be better for the document to handle its own keypress routines. As fas as I see it, the way the messages are handled is as follows; the vtkMFCWindow implements a large number of the standard window message functions. These are then the ones that respond to messages, because the vtkMFCWindow generally has the focus. These functions then call the appropriate function within the current windowInteractor. Have I understood this right? So what would be the best way to get the vtkMFCWindow to share the messages Subclass the vtkMFCWindow and remove it's message handling and then get the application to handle all messages and pass only the interesting ones (to vtk) to the subclassed vtkMFCWindow? I think this is primarily a problem for key presses, since the vtkMFCWindow only responds to a small number and it would be nice to use other keys to perform other operations within the application. Most mouse interaction will probably relate to toolbar work or vtk interaction anyway (i guess). Any thoughts?

The problem was that the vtkMFCWindow does not respond to the clicks (despite the example having a function within it that appears to suggest it should), instead the mouse action seems to passed directly to the vtkWindowInteractor. To solve this problem I think I should be subclassing vtkWindowInteractorStyle, so that I can either remove the handling of right mouse click (so that the window handles it) or modify it to pass clicks directly to the CView class. Does this sound like a sensible approach? Or is there a better/more standard solution? I didn't want to set off programming without at least knowing that I heading in the right direction! Cheers, Mark ---------------------------------- 笔记说vtk的MFC框架编程中遇到的一个问题就是vtkMFCWindow的消息响应问题，现在我找到了一个捷径来解决这个问题，然后这个办法有点傻傻的，但是非常的实用，见上图，我在vtkMFCWindow的窗口里面点击了鼠标，窗口有了WM_LBUTTONDOWN的响应，并且弹出了对话框。修改很简单，就是在vtk的源文件里面找到vtkMFCWindow.cpp，以及vtkMFCWindow.h文件，然后修改这2个文件，甚至你可以在里面修改更多的消息映射方式，然后直接使用cmake的方式仅仅重新编译vtkMFC这工程，然后将编译好的dll文件和lib代替原先的dll和lib。方法虽然简单，但是总是觉得有点不爽，毕竟修改了源代码，不过如果不爽的话，可以考虑将vtkMFCWindow.cpp和vtkMFCWindow.h文件copy到你的工程，然后换个名字建立你自己的vtkmfc类就可以了，但是如果讲到最最好的方法，也是最最实用的方法就是完全看懂vtkMFCWindow的整个消息响应以及和vtkWindowInteractor之间的联系方式，然后全新的改写自己的CMyView类文件成为一个新的类系于“vtkMFCWindow”，嗯 ~~ AM 1：03， 成功修改并创建了自己的vtkMyMFCWindow类，并在里面封装了自己的消息响应函数，然后都可以不用那些个lib和dll文件了，嘿嘿ie~ 使用2层mc提取2个不同的iso值，不同的alpha，不同的color显示。 4层绘制的神经元细胞下载本文
